Electro-hydraulic walking clutch system of harvesting machine

Abstract

The invention belongs to the technical field of mechanical transmission, in particular to an electro-hydraulic walking clutch system of a harvesting machine. The system is composed of a hydraulic gearpump, a connecting hydraulic pipeline, a power-assisted clutch device, an electromagnetic reversing valve, a brake pedal device, a power source, a one-rod operation control device, a connecting wireharness and the like. Through the one-rod operation control device, automatic separation and multi-stage gear selection of the walking clutch are realized, the one-rod operation control device is loosened, the walking clutch is automatically combined, and the right foot steps on the accelerator pedal to walk, finally, the electro-hydraulic control of the walking clutch is realized, the left foot of the driver is thoroughly liberated; through right-hand electro-hydraulic control one-rod type operation, the functions of walking clutch separation, multi-stage gear selection, clutch combination, agricultural combined harvesting machine walking and the like are achieved, the labor intensity of a driver is greatly reduced, the product reliability is improved, the walking operation time is greatly shortened, the maintenance cost is reduced, the whole machine is safer and more reliable, and a user can obtain more benefits.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to an electro-hydraulic traveling clutch system of a harvesting machine. Background technique [0002] my country is a large agricultural country with a wide variety of crops. Traditional crop harvesting methods use manual operations, which are inefficient and labor-intensive. With the development of science and technology, more and more crops are harvested mechanically. At present, general-purpose harvesters, such as grain combine harvesters, peanut machines, corn machines, etc., mainly use the drive axle box with left pedal clutch and right manual shift. This operating mechanism is complicated to operate, labor-intensive and low in efficiency. , It is necessary to step on the clutch to cut off the power and then shift gears. When the clutch works in the half-clutch state, it is easy to cause problems such as sintering and damage to the clutch plate. In...

Problems solved by technology

[0002] my country is a large agricultural country with a wide variety of crops. Traditional crop harvesting methods use manual operations, which are inefficient and labor-intensive. With the development of science and technology, more and more crops are harvested mechanically.

At present, general-purpose harvesters, such as grain combine harvesters, peanut machines, corn machines, etc., mainly use the drive axle box with left pedal clutch and right manual shift. This operating mechanism is complicated to operate, labor-intensive and low in efficiency. , you need to step on the clutch to cut off the power before shifting gears. When the clutch works in the half-clutch state, it is easy to cause problems such as sintering and damage to the clutch plate
